The main organs involved in waste management are the skin, lungs, liver, and kidneys.
Functions of the blood circulation system: â Circulates OXYGEN and removes Carbon Dioxide. â Provides cells with NUTRIENTS. â Removes the waste products of the metabolism to the excretory organs for disposal. â Protects the body against disease and infection.â Clotting stops bleeding after injury.â Transports HORMONES to target cells and organs.
